Ukrainian President Volodymyr Zelenskyy said Friday that the world should "be ready" for the possibility that Vladimir Putin could use nuclear weapons in the ongoing war. 

Zelenskyy, speaking to CNN, made the remark a day after CIA Director William Burns said "given the potential desperation of President Putin and the Russian leadership, given the setbacks that they’ve faced so far militarily, none of us can take lightly the threat posed by a potential resort to tactical nuclear weapons or low-yield nuclear weapons." 

"Not only me -- all of the world, all of the countries have to be worried because it can be not real information, but it can be truth," Zelenskyy told CNN when asked for his reaction to Burns’ comments.

Ukraine’s Defense Ministry revealed Friday that, for the first time, Russia has started using long-range bombers in the ongoing war. 

Spokesman Oleksandr Motuzyanyk said the long-range aircraft are being used to attack Mariupol, according to Reuters. 

"The situation in Mariupol is difficult and hard. Fighting is happening right now. The Russian army is constantly calling on additional units to storm the city," Motuzyanyk reportedly said. "But as of now the Russians haven’t managed to completely capture it."

A U.S. official told Fox News on Friday that the latest assessment by the U.S. is that Russia's Moskva warship was struck by two Ukrainian missiles before it sank.

The U.S. believes the flagship of Russia's Black Sea navy was roughly 60 nautical miles south of Odessa at the time of the explosion.

Moscow has claimed the ship sank after a fire on board caused an explosion.

"During the towing of the cruiser Moskva to the port of destination, the ship lost its stability due to hull damage received during a fire from the detonation of ammunition. In the conditions of stormy seas, the ship sank," Russia’s Ministry of Defense earlier told state media. 

U.S. officials also said Friday it is unclear how many Russian sailors may have been killed in the attack due to lack of satellite imagery.

Mariupol’s City Council is warning Friday that Russia’s military is carrying out a "new level of cleansing" in the besieged Ukrainian city by not allowing residents to bury deceased civilians. 

In a Telegram post citing locals still trapped there, the officials also said "Russian troops have begun the process of exhuming bodies that were previously buried in the yards of residential buildings." 

"A new level of ‘cleansing’ of the occupiers," the post said. "The occupiers forbid the burial of people killed by them. In each yard they put their own overseer."

China said that its military staged exercises on Friday in response to U.S. lawmakers' official visit to Taiwan. 

Chinese Foreign Ministry spokesperson Zhao Lijian said that the drills conducted by the People’s Liberation Army’s Eastern Theater Command in areas opposite Taiwan were "a countermeasure to the recent negative actions of the U.S., including the visit of a delegation of lawmakers to Taiwan."

He pledged that China would "continue to take strong measures to resolutely safeguard its sovereignty and territorial integrity."

The trip – previously condemned by the Chinese government in a statement – comes amid continued fears that China may move to invade Taiwan, stoked due to Russia's invasion of Ukraine. 

Following China's increasing aggression in the region, some say Russia's actions may embolden China to take some of its own.

Russia warned the U.S. and NATO this week that there could be "unpredictable consequences" if they continue to send Ukraine "sensitive" weapons as it prepares to launch a massive ground offensive in eastern Ukraine, a report said Friday.

The Biden administration announced that another $800 million in security assistance would be sent to Ukraine Wednesday, including artillery, coastal defense drones, anti-aircraft and anti-tank armored vehicles, and Mi-17 helicopters. 

Pentagon press secretary John Kirby said the defense systems approved by the U.S. are "reflective of the kind of fighting that the Ukrainians are expecting to be faced with" as Russia focuses on eastern Ukraine.

Russia on Friday is claiming to have destroyed a factory in Kyiv that makes anti-ship missiles after confirming that the flagship vessel of its Black Sea navy has sunk.

The Moskva cruiser rose to prominence at the beginning of the war when a group of Ukrainian soldiers defending Snake Island told its operators to "go f--- yourself" instead of surrendering, according to Reuters. Moscow is now saying the warship went down after a fire on board caused an explosion, but Ukrainian officials say their forces struck it Thursday with two cruise missiles. 

"During the towing of the cruiser Moskva to the port of destination, the ship lost its stability due to hull damage received during a fire from the detonation of ammunition. In the conditions of stormy seas, the ship sank," Russia’s Ministry of Defense told state media.

Russian advances in the south and east of Ukraine floundered on Thursday, the General Staff of the Armed Forces of Ukraine claimed.

"In the Donetsk and Tavriya directions, the russian enemy's main efforts were focused on attempts to capture the settlements of Popasna and Rubizhne. It is not successful," the Ukrainian military said.

"Thus, in the territory of Donetsk and Luhansk oblasts, eight enemy attacks were repulsed in the past 24 hours, four tanks, six armoured personnel carriers, four infantry fighting vehicles, and one enemy artillery system were destroyed," Kyiv added.
